The Dyson V15 Detect, originally released in 2021, continues to outperform many of its newer competitors, including Dyson’s own latest models. That’s why it secured the title of Overall Runner-Up in our 2025 Vacuum Wars Awards. Despite being a few years old, the V15 Detect remains top-tier, delivering industry-leading suction, strong lab and real-world performance, and exceptional value compared to newer, higher-priced alternatives.
At Vacuum Wars, all cordless vacuum reviews are conducted using units we’ve purchased ourselves, with no input or funding from manufacturers, allowing us to deliver objective and trustworthy results.
The Dyson V15 Detect still sets the benchmark for cordless performance: its class‑leading 124‑inch sealed suction and 17.6 kPa unsealed pull lift everything from fine dust to chunky debris, while the Fluffy Optic™ head’s green laser reveals hidden hard‑floor dirt and an onboard particle sensor automatically boosts power when heavier soil is detected. Paired with the versatile Digital Motorbar™ for all surfaces, a real‑time LCD particle‑and‑battery readout, a removable battery with above‑average efficiency, and a trimmer 4.6‑lb handle for easy maneuvering, the V15 delivers flagship power, smart tech, and lasting value at a price well below many newer rivals—earning it Vacuum Wars’ 2025 Overall Runner‑Up for Best Cordless Vacuum.

Unmatched Suction Power
The V15 Detect still holds the highest sealed suction score in our testing, measuring 124 inches of water lift. This beats the newer Gen5 Detect at 112 inches and far exceeds the cordless vacuum average of 74 inches.
In terms of unsealed suction, the V15 Detect again leads with 17.64 kPa, just ahead of the Gen5 Detect’s 17.36 kPa, and dramatically higher than the category average of 0.58 kPa.
Lighter Weight, Better Handling
The V15 Detect is also more user-friendly in terms of weight. With a handle weight of 4.56 pounds, it is noticeably lighter than the Gen5 Detect’s 4.98 pounds, which improves maneuverability and makes it easier to use for extended sessions or on stairs.
Excellent Battery Efficiency
Battery life is another area where the V15 Detect excels. It earned a Battery Efficiency Score of 25.6 points, just behind the Gen5 Detect’s 27.3 points, and well above the category average of 18.8 points. It also features a removable battery, giving users the option to swap in a backup for longer cleans.
Advanced Tech and Smart Features
The V15 Detect is loaded with intelligent features that optimize cleaning performance and user experience:
- Auto suction adjustment that adapts power based on floor type
- A dirt sensor that increases suction when high levels of debris are detected
- Real-time LCD display showing battery life, power mode, and particle count
- Two advanced cleaner heads:
- Fluffy Optic™ cleaner head with a green laser that reveals invisible dust on hard floors
- Digital Motorbar™ cleaner head designed for all floor types, with built-in anti-tangle technology
- Hair Screw Tool, featuring a conical brush bar to prevent hair wrap on pet beds, upholstery, and car seats
Better Value, Same Excellence
While the Dyson Gen5 Detect won our 2025 Best Performance Cordless Vacuum award, the V15 Detect delivers nearly identical performance and smart features—but at a significantly lower price. It also continues to receive strong customer feedback, further reinforcing its value and appeal.
Final Thoughts
When all the data points are considered—from suction and filtration to battery performance, weight, and price—the Dyson V15 Detect remains one of the best cordless vacuums available.
It is a high-performance, intelligent, and dependable option that continues to lead the field, earning its place as our Overall Runner-Up for 2025.
